public void getDataSourceOntologyAndDescriptions(Model model)

Description copied from interface: DataSourceRegistry

Generates a graph containing the datasource ontology (the vocabulary used to configure data sources), the sourceformat ontology (vocabulary used to specify widgets for the UI) and descriptions of data source types registered within this registry. These descriptions use the Fresnel Display Vocabulary. Each one comprises a fresnel:Lens instance, with a list of all configuration properties needed by a crawler for this data source. Each configuration property has a fresnel:Format that specifies the widget that is to be used in the user interface, the widgets are chosen from those specified in the Aperture sourceformat ontology. This graph is stored in the provided model.
